Do you know which Koch brother wanted to date Marla Maples, but thought better of it after Donald Trump picked her up?

How about which Koch brother donned a "Captain Koch" costume at the Wichita Gridiron Club?

Do you know which Koch brother wrote a play that provided source material for the film "Shakespeare in Love?"

How about which Koch brother opened up a bookstore, a John Birch Society bookstore?

Did you even know there were four Koch brothers? Senate Majority Leader Harry Reid, D-Nev., only talks about two of them, Charles and David, while leaving Bill and Frederick largely out of the equation.

Mother Jones Senior Editor Daniel Schulman tells the tale of the K-Bros masterfully in his new book "Sons of Wichita: How the Koch Brothers Became America's Most Powerful and Private Dynasty," and he'll drop by Roll Call Book Club on Thursday night to discuss not just the history of the Koch family and its behemoth Koch Industries, but the people behind it.

Be prepared. These folks play hard ball, especially with one another for control of a vast enterprise. How else to explain the Koch brother who subpoenaed his own mother, after she'd had a stroke, to testify in a lawsuit?
